What is Core Java?

In learning Java programming language, it may be hard to understand the basic terms of Java: Core Java and Advanced Java. So before digging into the Java tutorial concept, little do you know about core Java and Advanced Java?

Core Java
Advanced Java

Core Java: Sun Microsystem uses the term Core Java. A basic version of Java refers to the collection of libraries rather than the programming language. It is a standalone Java application that covers various topics like the OOPS concept, operators, data types, wrapper classes, collection & and exception handling.

Advanced Java: Advanced Java is also one of the parts of the Java programming language. But you can even say that the adventure is everything beyond Core Java. Advance Java, mostly the API, is defined in Java Enterprise Edition (JEE), including servlet programming and web Services. It combines web and enterprise application development, following client and server architecture.
